Reman: Like I said, In the past I've had a handful of packs "Go off" at me like fireworks after bad crashes (Usually with RC helis), So it's hard to get that image out of your head while stripping down Li-Po's. :)Today at 11:22:54

shawdreamer: the horror stories will always incite worry when messing about with Lipo's but its the same as everything else when working on electronics alike, alsong as your careful and methodical there's very little to panic about, I regularly recycle 4s's with a single dead cell into usable 3s packs, end of the days its alot more economical, safer and enviro friendly than having to bin them....just a pain that the dead cell is NEVER one of the outer cells so you always end up having to strip a good cell off to get at the bad cell before putting it back afterwards, its like dropping toast, it'll always land buttered side down and inevitably covered in pet fur Today at 00:11:16

Reman: Just did the one electrical job that still scares me. I dismantled some Lipo's with knacked cells and built usable packs out of the good cells. I've had packs go "VOOOOOOSH" at me in the past so I'm always slightly scared of having bare lipo contacts anywhere near what I'm working on, But all appears to have gone well and one of them is currently doing a charge/discharge cycle to make sure nothings a miss. :)January 20, 2019, 22:28:43

Reman: My original Dremel Pro made it to 14 years of heavy weekend use (And abuse) before it crocked. Dismantled that but it turned out to be a "Control module" fault, And Dremel made it ni on impossible to get into that without pooching it completely. January 20, 2019, 22:17:27

ched999uk: My 28 year old 12v 35w Weller soldering iron failed I didn't fancy forking out £100 for a new one. Stripped it down and found conductor snapped in cable. 10Mins later all back working great. I am very happy!!January 16, 2019, 17:23:06

shawdreamer: "look up there....its a drone!.....and whats this noise?..... no.....no..... it cant be!....NOOOOOOOO.......OOOOOOOOOOOOOPS I DID IT AGAIN, I PLAYED WITH YOUR HEAR....."January 10, 2019, 14:17:24

shawdreamer: tsk x2, just checked my thingiverse messages too... another a8 owner asking if one of my designs would work with his printer.... I said no as its not fire proof.... now he seems confused January 05, 2019, 15:35:09

shawdreamer: tsk.... a new Anet A8 owner asking for mod suggestions for his xmas first printer on thingiverse... I suggested a fire suppression system or atleast a wall mount for a fire extinguisher and smoke alarm..... he removed my post.... no helping some people January 05, 2019, 12:42:05

Reman: I did double check it with a metre (Mainly because I knew if I didn't check the polarity this would be the time the manufacturer had gone off script and put the negative in the middle of the coax) and felt slightly cheated because it was only making 19.7 volts. :)January 04, 2019, 14:01:11

Topic: Cannot bind R-XSR and Taranis QX7 (Read 7100 times)

I recently bought a Taranis QX7 (LBT EU) transmitter and also a R-XSR (LBT EU) receiver. I have installed Open TX 2.2.0 (17-02-12), then flashed the internal XJT module with the 'XJT_LBT_build151223.frk' (from FrSKy website) and also flashed the R-XSR with 'R-XSRLBT171009.frk' (from FrSKy website) via S.Port on the Taranis.

Next step is the binding between the Tx and the Rx, so as the manual says, I supply 5V (it accepts from 3.5V to 10V) to the R-XSR while pressing the F/S button. Red and Green LEDs stays solid and then I set the Tx into binding mode. Unfortunately, I do not know if I am doing anything wrong, but it does not work.

You are doing it the wrong way round.Put the radio in to bind Mose (it will start beeping you have to live with that for the duration of the process)Now power up the r-xsr whilst holding down the bind button.Wait a few seconds, power down the reciever, take the radio out of bind mode and power up the Rx, you should then get a solid green light

I have to say that I even bought a new R-XSR, but still the same issue. It is exactly the same as Michael Navigator. Thanks Michael for sharing a video with us. Which Open TX/ XJT module version have you installed in your Taranis QX7?

* Open TX 2.2. (just to eliminate all possible errors)* opentx-x7-eu-noheli-lua-en.bin created with the companion* TX eu1_170213.bin, * RC XSRLBT170619.frk

As mentioned, the R-XSR still does not work.

I tried the exact same procedure as used for the XSR. Only difference is the firmware of the RX* R-XSRLBT171009.frkI also tried an older version and wrong versions (in my despair)* R-XSR_LBT_170904.frk* XSRLBT170619.frk* XM+LBT170313.frk

Ok mate, so cool on the xsr, I was under the impression that was what you had done already.

On the last three bullet points, only one of those firmwares are for the r-xsr.Flashing with firmware for other hardware (the second is for the xsr and the third is for the xm+) is not only not going to work but a very bad idea as it can brick the board by changing the chip pin layout.

I notice the r-xsr firmware you use, whilst the latest, is nit at a version as high as the firmware on the xsr that worked.I therefore think the problem is the version of firmware on your internal module will not talk to the (older) r-xsr firmware.

You could try flashing am older version of the internal module firmware, otherwise contact the supplier.

On the radio open tx is the operating system, it is not on the internal module.Binding takes place between the internal module and the Rx, that is why the version of opentx is irrelevent

Same here, I finally contracted FrSky support. But all i received so far was: "Thanks contact us, maybe the problem is the firmware, i have feedback the problem to our test team, any new information i will tell you." ;-)Anyway, the new Firmware you posted works. :-)

Many thanks to you guys.

Here is the video in German:

I'll post a link in die video description to the forum so ppl can download the file as long as it's not available directly from FrSky. I hope that's fine with you.

Updated my 9XDwith the options of eu, lua, noheli and english via OpenTx to 2.2. Bootloader is already 2.2. Downloaded latest firmware of r-xsr from frsky site and also downloaded and tried the file above this post. Turned on 9XD with both trims held to get to bootloader. Connected usb to back of 9XD, transferred latest firmware to sd card of Tx. Unplugged USB, turn Tx off then plug in lead for firmware update connected to back of Tx with Rx connected to it, hold Menu the Page, go to Firmware look for firmware file, then long press to update external then ENT to confirm to update, wait for it to finish. Turn Tx off and unplug Rx.I've powered the receiver via the main board as I've already soldered them and before you say it I've also powered it via 6v power supply because I've got another lead from another receiver which is also not binding. Go through the binding process and the blue, red, and green lights remain solid.

Sorry mate but at no point there did you state you had connected the r-xsr physically to the radio, did you do that?Nor did you state you had updated the radio (opentx is not the firmware, you need to update the internal module on the radio as well as the Rx to a version that talks to each other

Maybe I've got it wrong regarding updating Tx via opens 2.2 app where you run app (OpenTx) on PC then choose which version you want to load into Tx like: which raďio, what language, whether EU or not, with or without Lua scripts etc. Then download using opens app then put Tx into bootloader connect USB to back of Tx click write to Tx then turn off and unplug USB lead from PC. Could you please let me know how exactly to update firmware of 9XD?

The 2 videos show exactly what I previously did with my Tx. No problems with the Tx after the upgrade. I have also tried to use the firmware from the Frsky website and that firmware corrupts the Tx, I just get a blank screen a random warning now and again. I have reverted to the OpenTx firmware again and still not able to bind them. I have contacted Quadcopter.co.uk for them to test to see if it's my radio that is not working. If I flash an international firmware on it via opentx then it works with my QX90 perfectly so I don't think it's my radio. This is my first foray into Frsky and Taranis. I am an experienced rc flyer and a club examiner with 'B' Cert. so I'm not unfamiliar with rc.Thanks.

Once again, opentx is not the firmware,You don’t need to change opentx at allWhat needs to match is the Frsky firmware on the internal module (not opentx) and the firmware on the Rx, don’t understand why you are playing with opentx

Thanks Paul01 that clarifies things formea whole lot. I thought xjt modules are other external modules you plug to the back of the Tx like the transition a while back from 35mhz to 2.4Ghz on futaba Tx where you plug in a different module to the back of the Tx. I'll try updating that when I get home. Thanks again.

No problem, its a topic that confuses most as you are right in thinking the XJT is an external module, the Taranis just comes with one internally, they are both treated the same from a firmware point of view other than one you choose flash internal and the other external.
